If I forget to turn off the headlights when I shut off my 2017 Prius, there’s no warning sound. Every other car I have driven sounds a warning. Is there any setting to activate a sound? If there is, I cannot find it.
The lights will shutoff automatically after a delay. This goes for Auto, Parking and On settings. You never need to move the light switch to Off. There is a vehicle setting where you can set the delay before shutoff, or maybe even disable it entirely.
